BED-BOTTOM FABRIC.

Specification of Letters Patent.

Patented Jan. 24, 1911.

Application filed May 8, 1908. Serial No. 431,628.

To all whom it may concern:

Be it known that I, CHARLES B. FnaLnY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed-Bottom Fabric, of which the following is a specification.

This invention relates to elastic bed-bottoms and is composed of a series of structuralunits assembled and interlocked together in the completed fabric, as will be hereinafter set forth in detail.

The object of this invention is to provide a bed-bottom fabricthat will retain its elasticity indefinitely and the component parts return to their relative normal posi- -tion when the load or weight to which the same may be subjected is removed.

A further object is to provide a wire fabric that can be easily and cheaply made and the parts entering into the completed structure quickly assembled.

Figure l is a plan. F ig. 2 is a view in perspective of a part of a bedebottom fabric embodying the improved features.

A may represent the bedebottom fabric in its entirety, B one` of the end bars of the supporting frame, and C a series of helical springs forming an elastic connection between the fabric and the respective end-bars of the frame, only one end being shown, but it will be understood that both ends are alike in the complete structure.

The fabric is composed of a plurality of wire units which are duplicates of each other and which go to make up a number of sections, so that a description of one unit and section will answer for the whole, the same reference characters being used on implicate parts in caen 'si-(tion.

The fabric structure is made up of a number of sections of which two and a portion of the third is shown and will be referred to as sections 8, 4 and 5. These sections extend transversely from edge to edge and are made up of a number of angulated units G, as best shown in Fig. 2. The units 6 consist of a transverse rod 7, the companion parallel longitudinal rods S and 9. The bend made in the units in forming the parallel rods 8 and 9, provides a loop 10 at their junction. The initial hook-end 1l, of the outside intermediate units along each edge, engage the eyes 12 formed in the border wires 13; the terminal hook-end lll engaging the loop 10 of the adjacent end of the next joining sectionV in the operation of assembling the parts. The corresponding hookends ll of the inside links are made to engage their respective loops l0, as is also the terminal hook ends 14; of the units in the next joining section. The initial and terminal hook ends of the units forming the respective end sections, are made to engage the loops l5 of the springs C connecting the wire fabric with the end bars of the supporting frame.

In this construction the rod or part 7 of each unit forms the transverse connection in the make up of each section, and the companion parallel rods 8 and 9 the longitudinal connection when in their assembled relation, as clearly shown in the drawing.

The units are easily and cheaply made and may be conveniently assembled by unskilled labor.

IIaving thus described my mvention,w11at I claim is l. A bed-bottom fabric, consisting of a number of sections, each section being made up of a series of angulated wire units, comprising a transverse rod-part and companion longitudinal rod-parts extending at right angles thereto, the respective ends of said units having engaging hook-ends and loops at the junction of said longitudinal rod-parts.

2. A spring bed-bottom, consisting of a numbell of sections, each section being composed of a number of wire units, each unit comprising a transverse rod-part and companion parallel rod-parts extending at right angles thereto, the respective ends of said rod-parts terminating in hook ends and a loop junction formed intermechate therewith.

In testimony whereof I ailix my signature, in presence of two witnesses.

CHARLES B. FRALEY.
